Patients with refractory and/or recurrent neuroblastoma have poor prognosis despite complex multimodal therapy; therefore, novel curative approaches are needed. The investigators are attempting to use T cells obtained directly from the patient, which can be genetically modified to express a 4th generation GD2-specific chimeric antigen receptor (4SCAR-GD2). The chimeric antigen receptor (CAR) molecules enable the T cells to recognize and kill neuroblastoma through the recognition of a surface antigen, GD2, which is expressed at high levels in neuroblastoma but not at significant levels on normal tissues. This study will evaluate the side effects and the best dose of a novel 4th generation anti-GD2 CAR T cells to refractory and/or recurrent neuroblastoma.
